A novel K2S2O8-promoted oxidative cyclization of enamines is described. A variety of enamines having diverse functional groups and substitution patterns react well using K2S2O8 as the oxidant in the absence of catalyst. This protocol provides a very simple route for the synthesis of polycarbonyl pyrroles and has the advantages of readily available starting materials, mild reaction conditions, and a wide scope of substrates.

A novel and efficient copper-catalyzed homocoupling of ketoxime carboxylates has been developed for the synthesis of symmetrical pyrroles. This reaction tolerates a wide range of functional groups and provides a synthetically useful process to synthesize
Synthesis of 2,3,4,5-tetrasubstituted pyrroles from aromatic ketoximes using the TiCl4/Et3N reagent system
Periasamy, Mariappan,Srinivas, Gadthula,Seenivasaperumal, Muthu
